Certification
|
Leak
rate of 3.0 gph at 10 psi* with PD = 100% and PFA = 0%.
Leak rate of 0.2 gph at operating pressure with PD = 100%
and PFA = 0%.
Leak rate of 0.1 gph at 1.5 times operating pressure*
with PD = 100% and PFA = 0%.
*Since leak rate varies as a function of pressure, this
leak rate and pressure were certified using an equivalent
leak rate and pressure, in accordance with an acceptable
protocol.
|
|
Leak
Threshold
|
2.5
gph for leak rate of 3.0 gph.
0.17 gph for leak rate of 0.2 gph.
0.09 gph for leak rate of 0.1 gph.
A pipeline system should not be declared tight if the
test result indicates a loss that equals or exceeds this
threshold.
|
|
Applicability
|
Gasoline,
diesel, aviation fuel.
Other liquids may be tested after consultation with the
manufacturer.
|
|
Specification
|
System
tests pressurized fiberglass and steel pipelines.
Tests are conducted at operating pressure.
System will not function with a mechanical line leak detector
installed in the pipeline.
|
|
Pipeline
Capacity
|
Maximum
of 100 gallons.
|
|
Waiting
Time
|
None
between delivery and testing.
None between dispensing and testing for leak rate of 3.0
gph.
Minimum of 45 minutes between dispensing and testing for
leak rate of 0.2 gph.
Minimum of 2 hours between dispensing and testing for
leak rate of 0.1 gph.
|
|
Test
Period
|
Response
time is less than 1 minute for leak rate of 3.0 gph.
Response time is 30 to 45 minutes for leak rate of 0.2
gph.
Response time is 32 to 48 minutes for leak rate of 0.1
gph.
Test data are acquired and recorded by a microprocessor.
Calculations are automatically performed by the microprocessor.
|
|
System
Features
|
Permanent
installation on pipeline.
Automatic testing of pipeline.
Preset threshold.
Single test to determine if pipeline is leaking.
Pump shutdown (optional), message display and alarm activation
if leak is declared.
|
|
Calibration
|
Equipment
must be checked annually for capability of detecting a
line leak of 3.0 gph and, if necessary, calibrated in
accordance with manufacturer's instructions.
